So, I got this website that is setup in Joomla 1.5.23 and the front page is used, and somewhat, at the moment, has resemblance to a blog (ie; has about 3 article 'excerpts' and a 'view more' button at the bottom that takes you to a page with a bunch more articles - not full articles, but again excerpts of about a paragraph long of them, before their cut off.)

So, how could I approach going in and making it look like/ and function like a blog where it A.) Displays the whole article and isn't restricted in length and cut off like an excerpt B.) Keeps it like an excerpt but at least has a 'read on' option that takes the viewer to the 'full' article.

Is there a component that I could try to do this with, does this go deeply into 'Templating', is it just a matter of swapping out dimensions within CSS?
